1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Growth in liquid media is the gold standard for detecting microorganisms associated with bloodstream infections. The Gram stain provides the first clue as to the etiology of infection, with phenotypic identification completed 1 or 2 days later. Providing more detailed information than the Gram stain can impart, and in less time than subculturing, would allow the use of more directed empirical therapy and, thus, reduce the patient's exposure to unnecessary or ineffective antibiotics sooner. The study had two objectives, as follows: (i) to identify new targets to improve our ability to differentiate among certain enteric gram-negative rods or among certain Streptococcus species and (ii) to determine whether real-time PCR and pyrosequencing could as accurately identify organisms directly from positive blood culture bottles as culture-based methods. Two hundred and fifty-five consecutive positive blood culture bottles were included. The results showed a high level of agreement between the two approaches; of the 270 bacteria isolated from the 255 blood culture bottles, results for pyrosequencing and culture-based identifications were concordant for 264/270 (97.8%) bacteria with three failed sequences, and three sequences without match. Additionally, compared to the universal 16S rRNA gene target, the new 23S rRNA gene targets greatly improved our ability to differentiate among certain enteric gram-negative rods or among certain Streptococcus species. In conclusion, combining real-time PCR and pyrosequencing provided valuable information beyond that derived from the initial Gram stain and in less time than phenotypic culture-based identification. This strategy, if implemented, could result in a more directed empirical therapy in patients and would promote responsible antibiotic stewardship.
